WINDOW 'V'EN'TILATOR Application led February 8, 1929. Serial No.338,555.

This invention relates to improvements in ventilators. A

The primary object of this invention is the provision of an improvedventilator which is L used upon a conventional sliding or movable windowsash, in a cooperative relation with the frame and window glass thereof,and by means of which a room may be ventilated without direct draft, andin such relation that the window in which the ventilator is built may belocked against unauthorized opening. A further ob]ect of this inventionis the provision of a compact and neat Ventilating device for use uponwindow sashes, prefer- 5 ably upon the lower portion'thereof in suchmanner that the ventilation may be readily closed off to prevent rainand the like from entering a room. v d

A further object of this invention is the i provision of a novel windowventilator comprising a cooperative closure portion and a screen portionmovably related with the .frame of an opening whereby to close oi theopening or open the same in a screened rela- 1 55 tion for Ventilatingpurposes.

Other objects and advantages of this invention will be apparent duringthe course of the following detailed descriptlon.

In the accompanying drawings, forming a part of this specification, andwherein similar reference characters designate corresponding partsthroughout the several vlews,

Fi res 1 and 2 are transverse sectional views taken through the improvedventilator and showing the adjustable relatiorrof parts thereof upon awindow sash.

Figure 5 is a perspective view of an end shield constituting part of theframe of the ventilator.

Figure 6 is a perspective view showing the metal supiorting stripattachable to the sill or other Arame part of an opening for eiliientlysupporting other parts of the ventiator.

Figure 7 is a fragmentary view showing the relation in which the partscooperate upon a conventional windowA sash, for ventilatlon; the windowsash pane being omitted.

In the drawings, wherein for the purpose of illustration is shown only apreferred embodiment of the invention, the letter A may generallydesignate the improved ventilator, which is used upon a frame B. In thepresent instance the frame B is a window sash, but it may be any otherframe through which ventilation is accomplished, such as a door frame,or the like.

The sash B includes the lower rail or stile 10, and side stiles or framepieces 11. The window pane 12 is secured against the beads 13 of therails of the window sash in conventional relation, except` that at itslower edge it terminates short of the lower rail or stile 10, for anyapproved distance, to deiine an opening 15b through which thevenltilating draft passes, as permitted by the ventilator A.

The improved ventilator A preferably comprises a supporting base 15,movably supportin the draft detlecting shield 16, to which end shields17 are connected, in a relation that will permit the oscillatorymovement of the shield 16 upon the base 15; the end shields 17constituting the frame of the windshield apparatus also detachablyreceiving'a perforated screen 19.

The metal strip base 15 is adapted to be secured upon the upper edge ofthe conventional wlndow sash lower rail 10. It includes a troughconsisting of a bottom 20, having upwardly extending divergent flanges21 and 22 adapted to respectively extend towards the inner and outersides of the window, and providing a trough-way therebetween whichreceives the movable portions of the windshield to be subsequentlydescribed. The outer flange 22 is doubled upon itself and extendsdownwardly. at 24. for abutment against the normal window pane engagingbead of the lower rail 10, and at its 100 go 27s-.a t cured at upon therail 16, to hold the trough in place.

The general nature of the ventilator is that ci? an imperorate shieldand a perforated screen arranged in a ti-shaped relation and held insuch relation by means of the end shields 17.

The end shields 17 are preferably of sheet metal. Each consists of asegmental body portion 30, which is convexly arcuated at its l upperedge 31. Along` the outer longitudinal edge the end shield 17 isprovided with an offset channel 33, which is offset beyond the outerplane surface of the bodv 30, and pro- -vides a socket 34 facinginwardly- Along thc opposite longitudinal edge the said body 3 0 hassoldered or otherwise formed therewith a channel-shaped socket 36,projecting from the inner side of the planeof the body 30 and defininga. socket opening 37. The channels 33 and 36 are arranged in a V-shapedrelation.

The imperforate shield 16 is preferably.

of glass. although it maybe of any approved material, even sheet metal.At its opposite end edges it is secured in the inner channels 36 of theend shields 17. The shield 16 may be detachably secured in thisrelation, to the tend shields 17 and along its upper marginal portion itprojects upwardly above the end shields 17, and thereabout at oppositeends and along the top thereof it is faced with. channel framing 40, asa protecting and guarding expedient. Flexible or bendable retainingtongues 41 are secured on the edging 40, at opposite side edges of theshield 16, adapted to be detachably anchored in suitable openingsprovided in the end shields 17. to prevent the accidental detachment ofthe shield 16 from the end shields 17.

The screen 19 is preferably of the conventional gauze type, including awire gauze or perforated body 15il secured in marginal framing 45. Theside frame pieces of the screen 19 are receivable in the sockets 34 ofthe channels 33 above mentioned. This positions the screen 19 in aV-shaped relation with the imperforate screen 16. The screen 19 is heldin the sockets 34 by bottom clips 34, shown in Figure 5.

It should be noted that the channels 33 terminate short of the lower endof the end shields 17 which seat in the trough of the base 15, to permitof an eflicient rocking action of the ventilator upon the base 15. Thescreen 19 does not seat along its lower margin in the trough, but isprevented by means of a right angled flange or stop 50, formed on thelower frame portion 45 of the perforated screen 19, as shown in Figure2; said fiange 50 at its free edge abutting the shield 16. This supportsthe perforated screen 19 convex ed es 31 of the end shields lie closelspaced be ow the lower edges of the s pane 12. The end shields lie inclose abutment with the retaining beads 13 of the side stiles 11 of thesash frame, as shown in Figure 7, and it is to be noted that thechannels 33 are in position for engagement with the pane facingshoulders on the retaining beads 13, to limit the movement of theventilator into the room. The flange 21 of course receives the lowermargin of the deflecting shield 16 thereagainst when the parts are in a.room Ventilating osition, as shownin Figure 2. When it is djesiredtoclose off the draft it is merely necessary to swing the ventilatoruntil the shield 16 is vertically positioned, and the shock absorbingtape or padding 60, on the pane facing side of the shield 16 will engagethe inside surface of the sash pane 12, as shown in Figure 1. Thisprevents breaking of the parts and enables a tight engagement of theshield 16 against the lower margin of the pane of the sash, in aweather-proof arrangement. 'lhe shield 16 may be held in this relationby means of a latch 62, having an inner thumb piece 63 extendingtransversely through the shield 16 and at its outer side having a crankfor latch engagement with the outer side of the pane 12, as shown inFigure 1. In order to prevent seepage of water to the trough, the ange22 is provided with transverse openings 66 at the bottom of the trough.The flange 50 acts as a Hoor to prevent the draining of water into thetrou h, and this Hoor 50 if desired ma be rovied with drain openin s, orthe endvshields adjacent thereto may suitably provided with drain openins.

It is inten ed that the opening in the sash for receiving the ventilatorshall be only about four inches in height. It is quite apparent that theventilator in this environment is of great ractical use, since thewindow can be locked) during use or disuso of the ventilator.

Various changes in the shape, s ize, and arrangement of parts may bemade to the form of invention herein shown and described, withoutdeparting from the spirit of the invention or the scope of the claims.
